Coincidence??

In the middle of the night last night Addie woke up panicked looking for Sullivan?  I had to wake her and tell her she was dreaming and that Sully was in his bed sleeping.  She calmed down and went back to sleep.  A few hours later Sullivan woke up screaming.  When I went up to get him he was crying for Addie.  Once he woke up fully he calmed down and as was fine.  That is probably one of the strangest things I have encountered while being the mom of these three crazy kids.  I would love to know what they were dreaming about.  Then again maybe I don't.
